Raspberry Pi headless server case

This is a case for a raspberry pi 3 or 4 (but it is easy to make own holders for it to adapt to different sized pi's) It is unique as it is intended for headless server use of the pi, so no screen connected to HDMI ports and acces the pi through SSH/SAMBA/FTP/etc.

First to install is the powersupply. Instead of an external power supply, the powersupply is integrated in the case. I use the 5V 4A switched power supply as commonly available on ali-express etc. It gives enough juice for the pi and and some USB devices. But it is also possible to fit in a smaller power supply. The supply is mounted with one 3mm bolt and nut on the fan side. On the front side it is hold into position by either another 3mm bolt/nut but I commonly leave it out as it is difficult to fit in the power supply and the power cable lock will make sure the supply stays in place.
Connect the power cable (there is also a hole for 6mm switches to power on/off)) and the 5V cable for the pi. I power the pi via the I/O
